Yeah I’m sure minimum wage clerks are going to totally feel comfortable asking the armed person (someone who believes they need to arm themselves to enter a shopping center) to please leave.

yeah, they probably would. Shooting someone is very fucking illegal.

also most larger establishments are going to have security, and, you can call the police if you wish.

Most people who have a concealed carry permit are generally law-abiding. I would certainly leave immediately if asked.
